+ | The System V Interface Definition is a series of publications describing the minimum required user and application interface expected of UNIX systems published as System V compatible. | ||
+ | |||
+ | As the SVID was more particular to UNIX System V, it contains many components not found in the POSIX standard. | ||
+ | |||
+ | From the introduction of the Fourth Edition: | ||
+ | |||
+ | The System V Interface Definition (SVID) is intended for use by anyone who must understand the operating system components that are consistent across all System V environments. | ||

+ | IEEE 1003.1, otherwise known as the POSIX standard, is published by the IEEE and is the current basis of the Single UNIX Specification as maintained and enforced by The Open Group. | ||
+ | |||
+ | While IEEE 1003.1 itself merely defines the C language interfaces for system services, additional 1003-family standards exist, such as 1003.2, defining the user-level commands available on UNIX systems. | ||
+ | |||
+ | From the foreword of IEEE 1003.1-1988: | ||
+ | |||
+ | The purpose of this standard is to define a standard operating system interface and environment based on the UNIX Operating System documentation to support application portability at the source level. | ||
+ | |||
+ | The foreword goes on to describe the derivation of this standard: | ||
+ | |||
+ | The various interface facilities described herein are based on the 1984 /usr/group Standard derived and published by the /usr/group Standards Committee, Santa Clara, California. |
